Name of the Condition

• Thyrotoxicosis factitia with thyrotoxic crisis or storm
• Also known as Factitious hyperthyroidism; may involve a thyrotoxic crisis or thyroid storm.

Summary

• This condition results from the excessive intake of thyroid hormones, leading to severe hyperthyroidism. A thyrotoxic crisis, or thyroid storm, is a life-threatening exacerbation of symptoms requiring urgent medical attention.

Causes

• Caused by the intentional or unintentional consumption of excess thyroid hormone medications, often in individuals self-medicating for weight loss or other reasons.

Risk Factors

• Use of thyroid hormone supplements without medical supervision.
• History of psychiatric conditions or Munchausen syndrome.
• Higher occurrence in individuals with access to thyroid medications.

Symptoms

• Symptoms include rapid heartbeat, anxiety, unexplained weight loss, heat intolerance, sweating, tremors, and possible heart failure. In a crisis, high fever, delirium, or coma may occur.

Diagnosis

• Diagnoses involve blood tests measuring thyroid hormone levels (T3, T4) and TSH, along with a physiological assessment and patient medication history.

Treatment Options

• Discontinuation of thyroid hormone intake is critical.
• Supportive treatments for a crisis may include beta-blockers for heart rate control, antithyroid medications, and hospitalization for severe cases.
• Treatment addresses both symptom management and underlying intake behavior.

Prognosis and Follow-Up

• The prognosis improves significantly with prompt treatment and cessation of hormone intake.
• Regular follow-up is necessary to monitor hormone levels and adjust treatments, along with psychological support if needed.

Complications

• Potential complications include heart failure, osteoporosis, severe weight loss, and mental health issues if untreated.

Lifestyle & Prevention

• Avoid unsupervised thyroid hormone consumption.
• Educating at-risk populations, particularly those seeking weight loss supplements, is crucial.

When to Seek Professional Help

• Immediate medical care is needed for symptoms of a thyrotoxic crisis, such as severe heart palpitations, fever, confusion, or loss of consciousness.

Tips for Medical Coders

• Ensure differentiation between exogenous hormone intake versus intrinsic gland overactivity.
• Be vigilant for documentation indicating self-administration of thyroid agents leading to crisis situations, to accurately code E05.41.
